BEST MODE FOR CARRYING OUT THE INVENTION

The present invention will be described below based on an embodimentshown in the drawings.

As shown in FIG. 1, in a containing bag 1 of a first embodiment of thepresent invention, an opening portion 2 a is formed at an upper endportion of a bag body 2 having a substantially rectangular flat shape,the inside of the bag is used as a containing section 3, a fastenerportion 4 parallel to the upper end portion is provided on the openingportion 2 a side, and a plurality of ventilation holding portions 5, 5 .. . are formed on one face side of the bag body 2 and above the fastenerportion 4.

The bag body 2 is formed of a resin film. As the resin film, a film madeof, for example, polyethylene, polypropylene, ethylene-vinyl acetatecopolymer, polyester, or the like can be used. It is preferable to use aresin film having a gas barrier property. It is especially preferable touse an aluminum-evaporated or laminated film, e.g., a film formed bylaminating polyester, aluminum, and polyethylene in this order from asurface side.

The bag body 2 is formed by folding one sheet of resin film to form alower end portion and both side portions are heat-sealed. A method ofsealing is not limited thereto, but sealing using a high frequency waveor an adhesive is also possible. Alternatively, two sheets of resinfilm, each having a substantially rectangular shape, may be overlappedwith each other and three sides may be sealed.

Although the bag body 2 of the embodiment has the substantiallyrectangular flat shape, the shape is not limited thereto, but may be anyshape such as a substantially elliptic shape or a slightly inflatedshape.

The fastener portion 4 is formed on inner faces of the bag body 2 and iscapable of sealing the containing section 3 by opening and closing. Asshown in FIG. 2, there is used a zipper in which a fitting portion 4 ahaving a bulging tip end with a substantially circular section and afitted portion 4 b with a substantially C-shaped section to be fittedover the fitting portion 4 a are disposed to face each other.

The fastener portion 4 not limited to the above structure but may be anystructure that can seal the containing section 3 by fitting.

As shown in FIG. 1 or 3, the ventilation holding portions 5 aresubstantially rectangular strips that can be inserted between thefitting portion 4 a and the fitted portion 4 b of the fastener portion 4and are formed on one face side (back face side in FIG. 3) of the bagbody 2 along the fastener portion 4 by forming a plurality ofsubstantially-vertical slits from the upper end portion side. Moreover,the upper end portion of the one face side is formed to be higher thanan upper end portion of the other face side to make it easy to pinch theventilation holding portions 5.

Although eight ventilation holding portions 5 are provided in theembodiment, the number of the portions 5 is not limited thereto, but anynumber of ventilation holding portions can be formed.

The ventilation holding portions 5 can be formed as an accordionventilation holding portion 5 a in which ridges and grooves extending ina vertical direction are alternately formed as shown in FIG. 4. Byforming the concave-convex accordion ventilation holding portion 5 aalong the fastener portion 4 in this manner, vents can be easily formed.

The shape of the ventilation holding portion 5 may be the substantiallyrectangular shape or any other shapes such as a shape having asemicircular tip end.

Although the ventilation holding portions 5 are provided on the one faceside in the embodiment, they may be provided on both face sides.Furthermore, although the ventilation holding portions 5 are providedthroughout the width of the upper end portion, the ventilation holdingportions 5 may be provided only at a part of the upper end portion.

Usage of the containing bag 1 of one embodiment of the present inventionwill be described below.

The fastener portion 4 of the containing bag 1 is opened and a sheet 7or the like emitting fragrance is contained in the containing section 3as shown in FIG. 1. Next, as shown in FIG. 3, the ventilation holdingportions 5 are folded so that tip end portions are inserted into thecontaining section 3, and positioned between the fitting portion 4 a andthe fitted portion 4 b of the fastener portion 4. In this state, thefitting portion 4 a and the fitted portion 4 b are fitted with eachother to close the fastener portion 4. Because the portion where theventilation holding portions 5 are inserted cannot be closed, itfunctions as a vent to diffuse the fragrance emitted from the sheet. Thecontaining bag 1 may be put into an inside pocket of a suit, a purse, orthe like and used like perfume.

It is possible to increase the amount of diffusion of fragrance byincreasing the number of the ventilation holding portions 5 to beinserted. On the other hand, it is possible to reduce the amount ofdiffusion of fragrance by reducing the number of ventilation holdingportions 5 to be inserted. In this way, the containing bag 1 of thepresent invention can regulate the amount of diffusion of fragrance.Moreover, because the ventilation holding portions 5 are formed at thebag body 2, there is no possibility of losing them.

In order to prevent emission of fragrance, the ventilation holdingportions 5 may be pulled out of the fastener portion 4 and the fastenerportion 4 may be closed to seal the containing section 3.

A sheet formed by kneading perfume of rose, lavender, or the like intocyclodextrin made from corn starch or the like and applying it onto asheet of paper or impregnating the sheet of paper with it may be used asthe sheet that emits fragrance.

As a modified example of the containing bag 1 of the embodiment, streakytear lines 6 may be formed substantially vertically from the upper endportion side of the bag body 3 as shown in FIG. 5(A) and ventilationholding portions 5 b may be formed by tearing the tear lines 6 as shownin FIG. 5(B). The tear lines 6 may be formed as streaks that are thinnerthan the other parts, may be formed by making holes of dotted lines, ormay be formed by stretching the film to facilitate tearing of the filmin the vertical direction.

Another embodiment of the containing bag of the present invention willbe described below. In the description, description of portions havingthe same structures as those in the first embodiment will be omitted.

The second embodiment of the containing bag of the present invention isa containing bag 11 having two containing sections 13 a, 13 b on thefront and back of a bag body 12 as shown in FIG. 6. Ventilation holdingportions 15 are formed at a partition face portion 18 to partition thecontaining sections 13 a, 13 b. By folding the ventilation holdingportions 15 forward or backward and inserting them into a fastenerportion 14, the vents can be formed at both the containing sections 13a, 13 b.

Although the ventilation holding portions 15 are formed at the partitionface portion 18 in the embodiment, they are not necessarily formed therebut may be provided on a front face or a back face of the bag body.Moreover, three or more containing sections may be formed.

In a containing bag of a third embodiment of the present invention, asshown in FIG. 7, four sides of a bag body 22 are sealed by heat sealingor the like in advance, an unsealing portion 28 where the bag body 22can be unsealed in a width direction and a fastener portion 24 areformed on an upper end portion side of the bag body 22, and a pluralityof streaky tear lines 26 extending from the upper end portion sidetoward the fastener portion 24 are formed on one face side (front sidein FIG. 7) of the bag body 22.

The unsealing portion 28 can be formed as a streak that is thinner thanthe other parts or may be formed by stretching the resin films tofacilitate unsealing in the width direction.

The unsealing portion 28 may be torn in the width direction and the tearlines 26 may be torn from the upper end portion side toward the fastenerportion 4 to form the ventilation holding portions 25.

Because the sheet or the like emitting fragrance can be sealed in thecontaining bag 21 in advance, the fragrance of the enclosed sheet isprevented from escaping before use.
